A stress analysis that describes the crystal growing process requires a material model that is valid over a wide temperature range and includes dislocation motion and multiplication. The stresses developed in the growing process could induce residual

Five Ni/Co bimetallic catalysts with loadings of 10% Ni, 7% Ni + 3% Co, 5% Ni+5% Co, 3% Ni+7% Co, and 10% Co were impregnated on Degussa silica by the incipient wetness technique. The catalysts were calcined at 400 °C for about 5 h in a furnace, and

The complex relationships among composition, roartensite start and finish temperatures, morphology of the martensite, residual stress distribution, and quenching conditions produce significant microstructural changes through a carburized case. Variat

The mechanical alloying process continually deforms, cold welds, and breaks apart metal powder particles. During the process of mechanical alloying elemental crystalline powders can produce an amorphous alloyed powder. Consolidation of these powders

During the growth of CZ silicon crystals, dislocation motion and generation are induced by the thermal stresses which arise from rapid cooling from the solidification temperature. These defects limit the fraction of acceptable silicon device chips ob

In situ X-ray diffraction was employed to characterize the structure of several cobalt catalysts on a silica support. The catalysts were reduced in flowing hydrogen at 350 °C for about 16 h and X-ray diffraction patterns were collected. After reduct

Y-, Dy-, and Gd-doped neodymium (Nd) superconductors (RE/sub 0.1/Nd/sub 0.9/Ba/sub 2/minus//Cu/sub 3/O/sub y/) exhibited sharp resistivity transitions at 92 K. DC susceptibility measurements gave a common curve with diamagnetic onsets at 93 K and tra

Changes in the average particle size and particle size distribution (PSD) were monitored during sintering of a silica-supported nickel catalyst. Sintering was carried out in nitrogen and hydrogen atmospheres from 500 to 800 °C for times varying from
